Multi-modality imaging of the aortic valve in the era of transcatheter aortic valve replacement: a guide for patient selection, valve selection, and valve delivery

Advances in induced pluripotent stem cells, genomics, biomarkers, and antiplatelet therapy highlights of the year in JCTR 2013

The Journal provides the clinician and scientist with the latest advances in discovery research, emerging technologies, preclinical research design and testing, and clinical trials. We highlight advances in areas of induced pluripotent stem cells, genomics, biomarkers, multimodality imaging, and antiplatelet biology and therapy. The top publications are critically discussed and presented along with anatomical reviews and FDA insight to provide context.

Is there a need for bacterial endocarditis prophylaxis in patients undergoing urological procedures?

Heart valve repair or replacement is a serious problem.The focused update on infective endocarditis of American College of Cardiology/American Heart Association 2008 (ACC/AHA guidelines) and Guidelines on the prevention, diagnosis, and treatment of infective endocarditis (new version 2009) of the European Society of Cardiology (ESC guidelines) describe prophylaxis against infective endocarditis as not recommended for urinary tract procedures in the absence of active infection. A statistical association has been recently shown between urological procedures and the development of infective endocarditis. New evidences concerning infective endocarditis due to Actinobaculum schaalii, Neisseria gonorrhoeae, Streptococcus agalactiae, Enterococcus faecalis, Pseudomonas aeruginosa, Aerococci and Staphylococcus aureus, and new findings indicate there is a need for bacterial endocarditis prophylaxis in patients undergoing urological procedures especially in elderly patients and in cancer and immunocompromised patients, to avoid serious consequences.

Is there a need for bacterial endocarditis prophylaxis in patients undergoing gastrointestinal endoscopy?

Heart valve repair or replacement is a serious problem. Patients can benefit from an open dialogue between both cardiologists and gastroenterologists for the optimal effective patients care. The focused update on infective endocarditis of the American College of Cardiology/American Heart Association 2008 (ACC/AHA guidelines) and guidelines on the prevention, diagnosis, and treatment of infective endocarditis (new version 2009) of the European Society of Cardiology (ESC guidelines) describe prophylaxis against infective endocarditis (IE) as not recommended for gastroscopy and colonoscopy in the absence of active infection but increasing evidence suggests that the role of IE antibiotic prophylaxis remains a dark side of the cardio-oncology prevention. New evidences concerning infective endocarditis due to Streptococcus bovis, Streptococcus agalactiae, Enterococcus faecalis, Enterococcus faecium, Enterococcus durans, and new findings indicate that there is a need for bacterial endocarditis prophylaxis in patients undergoing gastrointestinal endoscopy especially in elderly patients and in cancer and immunocompromised patients, to avoid serious consequences.
